The Basics Supply and Demand

The Basics Supply and Demand Supply and Demand analysis is relatively straightforward once the terminology is understood. The important terms are as follows: PriceQuantityDemand and Demand CurveQuantity DemandedSupply and Supply CurveQuantity SuppliedEquilibriumSurplusShortage Basic supply and demand analysis is done one of two ways - either graphically or numerically. If done graphically, it is important to set up the graph in the standard form. The Graph Traditionally economists have placed price (P) on the Y-axis and quantity (Q), as in quantity consumed or quantity purchased/sold on the X-axis. An easy way to remember how to label each axis is to remember P then Q, since the price (P) label occurs above and to the left of the quantity (Q) label. Next, there are two curves to understand - the demand curve and the supply curve. The Demand Curve A demand curve is simply a demand function or demand schedule represented graphically. Note that demand is not simply a number - it is a one-to-one relationship between prices and quantities. The following is an example of a demand schedule: Demand Schedule $10 - 200 units$20 - 145 units$30 - 110 units$40 - 100 unitsNote that demand is not simply a number such as 145. The quantity level associated with a particular price (such as 145 units $20) is known as a quantity demanded.A more detailed description of the demand curve can be found at: The Economics of Demand. The Supply Curve Supply curves, supply functions, and supply schedules are not conceptually different than their demand counterparts. Once again, supply is never represented as a number. When considering the problem from the point of view of the seller the quantity level associated with a particular price is known as quantity supplied. A more detailed description of the supply curve can be found at: The Economics of Supply. Equilibrium Equilibrium occurs when at a specific price P, quantity demanded quantity supplied. In other words, if there is some price where the amount buyers wish to buy is the same as the amount sellers wish to sell, then equilibrium occurs. Consider the following demand and supply schedules: Demand Schedule $10 - 200 units$20 - 145 units$30 - 110 units$40 - 100 units Supply Schedule $10 - 100 units$20 - 145 units$30 - 180 units$40 - 200 unitsAt a price of $20, consumers wish to purchase 145 units and sellers which to provide 145 units. Thus quantity supplied quantity demanded and we have an equilibrium of ($20, 145 units) Surplus A surplus, from the supply and demand perspective, is a situation where, at the current price, quantity supplied exceeds quantity demanded. Consider the demand and supply schedules above. At a price of $30, quantity supplied is 180 units and quantity demanded is 110 units, leading to a surplus of 70 units (180-11070). Our market, then, is out of equilibrium. The current price is unsustainable and must be lowered in order for the market to reach equilibrium. Shortage A shortage is simply the flip-side of a surplus. It is a situation where, at the current price, quantity demanded exceeds quantity supplied. At a price of $10, quantity supplied is 100 units and quantity demanded is 200 units, leading to a shortage of 100 units (200-100100). Our market, then, is out of equilibrium. The current price is unsustainable and must be raised in order for the market to reach equilibrium.Now you know the basics of supply and demand. Have additional questions? I can be reached via the feedback form.

Choose the Best Time to Study for Finals

Choose the Best Time to Study for Finals With finals coming up in just a couple weeks, a lot of students start planning their studying schedules. However, theres an important factor to take into consideration when making a plan: when do you study best? Youve heard of â€Å"morning† and â€Å"night† people, right? Some people simply function better in the morning than at night while others struggle to get out of bed in the morning but have no problem burning the midnight oil. Each individual has times during the day when their brain is more alert and theyre able to assimilate and process information as well as create and produce. Trying to push through during the other hours can not only be unproductive, it can also be counter-productive. Thats because the study session wont have been successful, leading to burn-out and discouragement. Finding out the best time to study can help you make the most of your limited time during finals season. Why It Matters During Finals During finals period, this concept is particularly relevant. By identifying when youre most alert, you can plan a study schedule that allows you to maximize your productivity. You can choose to rest or do other activities during your less productive hours to make sure you can make the most out of your â€Å"on† time. How To Identify Your Most Productive Time Most people have an instinct for when theyre most productive. If you tend to be bright and ready for the day in the morning but hit a slump after lunch, and tend to knock off early, falling asleep while reading at 9p.m., you can assume that mornings are your best time. If mornings are tough for you and you generally need a landslide of caffeine to get you moving, slowly working your way up to speed as the day wears on and peaking at night after dinner, then your nights will be your most productive times. Some people have slow mornings and early nights but tend to burst with energy in the afternoons. In that case, your most productive time will be during the afternoon. Of course, the best way to be sure is to test this theory out. Choose to study in the morning, afternoon and night and see which one works best for you. If you have the chance to give this a test drive before the finals season hits, it could really help you make the most out of your study time. How Can You Maximize Your Productive Hours? Once you discover your best working time, you should find ways to guard that precious time. Eliminate or at least limit your distractions as much as possible. A quiet, isolated place to study would be ideal so you dont run the risk of friends or family members interrupting you. Turning off phones or putting them on silent or vibrate is also a helpful way to keep distractions to a minimum. Dont tempt yourself with social media during these hours, either. Leave that for another time. Create a Pattern If you can create and stick to a schedule, it will be even more beneficial to your productivity. Adhering to a specific plan every day helps trigger the brain into â€Å"work mode† when its time for serious studying and can enhance your productivity even more. The more consistent you are, the better your work sessions will be. Dont just be consistent with your work, though. Being consistent with the things you do outside of your studying hours is also important. Exercise, eating, and sleeping routines also help keep the brain and body in top running condition. Many successful writers keep consistent schedules. Acclaimed author Haruki Murakami keeps a rigorous schedule of waking at 4am, writing for five or six hours, running or swimming or both and then reading and listening to music. Bed-time is 9:00pm. He describes this process of bringing himself into a kind of a trance with a repetitive pattern that he can rely on every day. Whichever time of day is best for your studies, make sure to get the most out of it by limiting distractions and making the most of your â€Å"off† time as well.

Critique of a research article (See below for article )) Essay

Critique of a research article (See below for article )) - Essay Example rect relation to the research gap outline in the above introductory paragraph, Sawyer and Penman (2007) address the impact of computer use on nursing practitioners. More specifically, they address the physical consequences of usage and whether or not nurses receive the required ergonomics training and implement it in their practice. This study will critique offer a comprehensive critique of Sawey and Penman’s (2007) article. The critique will commence with an overview of Sawyer and Penman’s (2007) article. Within the context of this overview, the rationale for the article will be explicated, a brief review of its selected methodology presented and, importantly, the importance of the article and its relevance to contemporary nursing practices will be fully articulated. Computers are becoming increasingly prevalent in the healthcare setting, and their potential applications and value are extensive. Computers store and process information that can be interconnected to various sources to transfer information from one source to another within the hospital and outside to the world at large. Within the field of nursing, computers can be used by nurses for the purposes of education and seeking information, facilitating communication, and patient documentation. While much of the literature focuses on factors contributing to computer utilization, few studies describe the actual computer utilization by nurses. The available literature identifies uses and benefits of computer access that are often anecdotal and assumptive. Computer technology is rapidly evolving, and research is not keeping up with examining and documenting its impact on the profession of nursing. In a profession focused on providing evidence based practice, current and relevant evidence is needed regarding, not just the actual application of computers by nurses, but the health-related impact of usage on nurses. The implication here is that the rationale for this article stems from the role which

Does NY stop and frisk reduce crime Term Paper Example | Topics and Well Written Essays - 250 words

Does NY stop and frisk reduce crime - Term Paper Example believe that the policy on â€Å"stop and frisk† has been quite effective in terms of reducing crime (Mac Donald, 2012). New York is not the only city that has tried to implement the â€Å"stop and frisk† policy. To make the criminals feel apprehended at the time of government election in 2008, the police department of Philadelphia also implemented the same policy. A couple of years after the Mayor’s election, the incidence of murder was significantly reduced by up to 22% (Lamberth, 2012). Answering the question â€Å"Does NY stop and frisk reduce crime?† is not easy to answer due to the fact that the real factor that could increase or decrease in the crime rate is very complex. Although Philadelphia mentioned that there was a 22% reduction in the number of reported murder, this figure does not necessarily mean that the process of implementing the â€Å"stop and frisk† policy was the root cause behind the decreasing trend in murder cases. In fact, Lamberth (2012) mentioned that the state of Philadelphia was already experiencing a decrease in the number of murder cases since 2006. Up to the present time, there is no scientific evidence that can prove that the process of implementing â€Å"stop and frisk† policy is effective in terms of reducing crime. The fact that the "black pedestrians were stopped at a rate that is 50 percent greater than their representation in the residential census" makes this policy develop racism and prejudism in New York (Neumeister, Hays, & Gross, 2012).

This chapter will provide a range of reviewed literature which will be relevant to the study which will speculate school environment in relation to performance of mathematics subject in Kimala secondary school. THE LACK OF TEACHING AND LEARNING MATERIALS AFFEC T MATHEMATICS PERFORMANCE.Anderson, B (1990:2) stated that, â€Å"Kilimanjaro region success in education sector is made possible by the donor who funded school teaching materials like mathematics books. Though Kilimanjaro region became the second after Dar-es-Salaam. † some schools in Kilimanjaro including Kimala secondary school receive support from world food program, international fund for agriculture development and other organizations which all together helps to feed schools and most students even those who are found among secondary schools in Kilimanjaro do not turn back home until they use evening time for studies.Mwendapole (2009:4) Reported that, â€Å"half of the students who attempted leaving certificate examination failed the Mathematics subject, as the minister for educational and vocation training announced publicly through radio and television. † The minister’s report showed that most students performed poorly in Mathematics subject. This was the indication that there is lack of teaching and learning facilities like Mathematics books, Mathematics teaching aids like manila and others.According to Ahiakwo, M. J (1989:295-6), A Crisis in the school of some countries is being caused by irrelevant curricula, in adequately trained teachers, lack of teaching materials such as Mathematics text books which are designed for use in teaching as whole or part of particular study course, reference books which are designed for use in teaching as whole or part of particular study course, reference books which contain collected information. Wickliffe N.J (1997:181) Said, drawings combine the features of both picture and charts in that they represent something that is real and at the same time, do so in form of summary, drawings are symbolized summaries of the real earth and it is important to remember this, for symbolism is code and children need to be taught to reach such codes. This significance of objects is depicting the whole situation of lacking in English teaching in secondary schools in Tanzania. CHAPTER THREE 2. RESEARCH METHODOLOGYThe research design was used especially cross section research design where the information for study was collected on time in which both question for students ad interview for the head of the school and academic matter were used. The researcher was able to access many people so that he made genuine interpretation and generalization to other subject by using this research design. Also the researcher was able to spend few hours to complete the whole process of collecting data by using survey research. 3. 1. INTRODUCTIONThe researcher will use the questionnaires method which includes both open and closed questions and the observation method whereby he will visit Kilimanjaro secondary school. The targeted population will be considered 3. 2.

The Physics of Roller Coasters Essay - 1483 Words

The Physics of Roller Coasters The roller coaster has its beginnings in Russia where during the 1600s. People crafted sleds out of wood and built hills made of ice blocks. The hills had sand at the bottom to help slow down the sleds so they would not crash when they reached the bottom of the hill.1 Over time, the roller coaster has become more complex. They now are taller, faster and are designed out of different materials like wood and steel. Although roller coasters are fun and exciting, the questions, what allows them to twist and turn, go up and down hills at a fairly good speed? Why do they not fall off of the track when it goes through a loop? The answer to these questions and others about roller coasters lies in the application†¦show more content†¦Then as the coaster begins its decent down the first hill, the energy is converted back into kinetic energy as the train is pulled toward the Earth by gravity. Gravity is the traditional source of power for roller coasters that accelerates the train as i t goes on its hilly, twisty journey.3 Gravity is a unit of acceleration, that is always present, that causes free-falling objects on Earth to change their speed at a rate of approximately 10 m/s (32ft/s) every second.1 So, as the train goes down the hills of the track it has a positive acceleration giving it the necessary potential energy to â€Å"climb† the next hill, make a turn, or travel through a loop. Also, as the train goes down the hills and loops, it experiences a free fall effect. This occurs when an object falls and is not inhibited by other objects2 (314-315). As the train goes down the hill, the coasters’ mass causes it to accelerate faster than the people in the car. During the free fall stages of the ride the train does not exert any pressure on the riders or the track causing the riders to feel momentarily weightlessness. This is why the train has wheels on the bottom of the track and the passengers of the train have some sort of restraining device to hold them into their seats.3 So, as the train goes down the hill it is actually falling, causing the velocity of the train to increase due to theShow MoreRelatedRoller Coaster Physics1483 Words   |  6 PagesIndividuals love to go to the amusement parks and try out the rides that are available.

Suddenly your body is flung forward as you plummet down the first drop. Then you are being forced down on the cart’s seat as you arch the bottom of the transition to going up the second hill. WindRead MoreThe Physics of Roller Coasters1551 Words   |  7 PagesPeople sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance, you may go to Six Fla gs and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia, gravitationRead MoreThe Physics Of Roller Coasters1209 Words   |  5 PagesEver since the first commercial roller coaster was built in the United States in 1884, roller coasters have been seen in amusement parks all around the world. These rides, seen in all shapes and sizes, are widely recognized for their thrills. At sudden twists and turns, riders experience large levels of excitement. But what makes a roller coaster so exciting? The answer is physics. In the process of designing roller coasters, engineers use concepts such as Newton’s three laws of motion to makeRead MorePhysics Principles Of Roller Coasters1047 Words   |   5 Pagesresearch topic was about the different physics principles that apply to roller coasters. I am to state not only the different types of principles but as well some laws of physics. Roller coasters are not an easy thing to build, one can yes build it but in order to make it succeed there are many ideas that come together and many calculations. I selected this topic because I never paid much attention to all of that work engineers have to do in order to make a roller coaster successful and also because I seeRead More Physics of Roller Coasters Essay1752 Words   |  8 Pages Roller coasters are driven almost entirely by inertial, gravitational and centripetal forces. Amusement parks keep building faster and more complex roller coasters, but the fundamental principles at work remain the same. A roller coaster is like train. It consists of a series of connected cars that move on tracks. But unlike a passenger train, a roller coaster has no engine or power source of its own. For most of the ride, a roller coaster is moved only by the forces of inertiaRead MorePushing the Sensory Human Experience: The Physics of Roller Coasters1469 Words   |  6 Pagesexperience? Physics allows roller coasters to give the human an adrenaline rush. With physics, engineers are able to mathematically calculate each experience a rollercoaster has without even having the rollercoaster built yet. The equations of the rollercoasters allow the engineer to know the forces released on the body, the speed and acceleration of the train, the energy lost due to friction and the resistance. Before the understanding of the theories derived from physics, roller coasters were limitedRead MoreNewtons Laws of Motion858 Words   |  3 PagesTo walk is not as hard as running, so less force is needed to succeed in doing it (Forester). This leads us to the third law of motion, for every action, there is an equal and opposite reaction (Newton’s Third Law). Another concept of Physics is moving water. For example, flushing the toilet, waterfalls and dams. Flushing a toilet is a great example of transferring energy. Usually on most toilets there is tan on the back of it filled with water. Water that is stored is a greatRead MoreThe Coaster Of The Roller Coaster1462 Words   |  6 PagesOur roller coaster is about three and a half feet tall and two feet wide. It has one loop, two funnels, three turns, one five-part zig-zag, and one pulley leading from the end to the top, and four bells that rang and vibrated when the marble hit them. Our group divided the work by, assigning people jobs, then switching after a while. An example of that some people would score and other group members would fold, or some would build and others would test, and we took turns switching jobs. SomethingRead MoreThe Structure Of Roller Coasters1038 Words   |  5 Pages The structure of roller coasters present many factors in physics and in engineering, engineers must contain an abundance of knowledge and research in order to assure the safety and the structure as a whole. AAPT needs entries at their annual roller coaster competition that include the use of only gravity to get from the beginning to the end of the track, so a structure will be built to present overall knowledge on kinetic and potential energy, as well as calculations. Relating to other fields, this
